High-yield cultivation of summer eggplant
Xia Qiuyu eggplant is an important vegetable for the off-season in August and September. Its growth period spans the summer high temperature season, and cultivation and management measures must be targeted. I. Variety selection: Choose heat-resistant, disease-resistant and high-yield mid-late-maturing varieties, such as Luqie 2, Jifeng 3 and Banyuan 1. Second, nurturing strong seedlings: Shandong Province, generally from late April to early May, Yangshuo seedlings exposed, sowing 5-7d soaking, germination. When sowing, fill the bottom water in the bowl. After the water infiltrates, sprinkle a layer of fine soil on the flour surface. Spread the seeds evenly on the fine wet soil. After sowing, cover the fine soil 2cm, and wait for the eggplant to grow to 2-3 pieces. When the leaves are divided into seedlings, the seedling distance is lOcm10cm, and the seedlings are watered in time and sprayed with 1000 times liquid plant power 2003 solution. After watering or after rainfall, the nutrient soil should be promptly spread on the bed surface. III. Management after planting and planting: Choose 4-5 years without planting solanaceous vegetable and easily draining plots. Mushi high-quality farmyard fertilizer is over 5000kg, diammonium phosphate is 40kg, and then the ridge is laid, spacing is 60cm, and plant spacing is 40cm. Planting seedlings should be planted with high soil. After the seedlings are planted, they are watered immediately. On the second day or the third day of planting, water must be poured one more time. After easing the seedlings, the cultivator and seedlings shall be promptly cultivated. Drain immediately after rain to prevent rooting. In order to reduce the occurrence of diseases such as eggplant blight, one can spray 200 times liquid equal volume of Bordeaux mixture. Fourth, the first fruit and fruit set management: In the flowering of the door to the fruit set, should control the watering, a section of seedlings. However, in order to avoid excessive drought caused by falling, but also need to be properly watered. After the rain or after the watering, the cultivator shall be cultivated in time. After the door is occupied, the pepper shall be topdressed and watered in a timely manner. The whole stalk shall be smashed, the lower leaves of the door and the lower leaves shall be removed, and the manure water shall be topped with 1000-1500kg per mu. Have to chase a fertilizer, each time Mushi urea 20kg, phosphate fertilizer 15kg, potassium fertilizer 1OOkg, in order to reduce the occurrence of eggplant M. blight and Brownie disease, should be regularly spraying chlorothalonil, mancozeb or Bordeaux mixture. V. Results-based management: The outcome period is in the rainy season, and management focuses on preserving the fruits and keeping the leaves. The old leaves and diseased leaves of the stems were removed in time, and the spraying of cotton was controlled regularly to prevent M. blight, brown-skin disease, and aphids, tea tree beetles, and red spiders. In order to meet the needs of the eggplant plants for nutrient, the ammonium sulfate is generally applied once every 10 to 15 days, each time 10 to 15 kg per mu, combined with spraying, plus 0.3% of urea or 0.2% of potassium dihydrogen phosphate as Foliar dressing is better. During the rainy season, it is necessary to pay attention to timely harvesting of fruits, which will not only help increase the yield and quality, but also reduce the rot in the rain.
